FULL-FORWARD Barry Hall has been dropped 'indefinitely' by the Swans, after accepting a one-match suspension for attempting to strike Shane Wakelin on Monday.

The club said Hall would be unavailable for selection for the immediate future, subject to assessment by the club psychologist.

Hall, who missed seven matches for striking West Coast's Brent Staker in round four this year, was charged with a level two offence of attempting to strike defender Wakelin during Saturday's match against Collingwood at ANZ Stadium.

Normally, the charge would attract 80 demerit points and a reprimand, but Hall's penalty was increased by 50 per cent because of his poor tribunal record.

Hall's carry-over demerit points further increased the penalty to 210 demerit points and a two-match suspension, but this was cut to one match with the 25 per cent reduction for an early guilty plea.

Paul Roos says it is not clear when Hall will return to the side after the Swans' psychologist recommended the spearhead be ineligible for selection until further notice.

"Unfortunately Hally won't play this week and we're not sure how long it will be before he plays. At the moment he's like a player who's ineligible for selection," Roos said on Monday.

"He put it on the agenda that he was working on some personal issues during that seven or eight weeks [when suspended after round four]. Probably the unfortunate side of it is that he probably has not been able to overcome those issues," said Roos.

"I'm not sure when he'll play again. That won't be determined by me but he's been working closely with Grant [Brecht, club psychologist] and we hope they can work through some issues and he can come back reasonably quickly, but when that is I don't know."

Hall became increasingly frustrated during the game with the number of free kicks he gave away against the wily Wakelin.

The Collingwood game was Hall's third since he returned from the Staker ban.

Roos said he only saw the incident on Monday morning as had members of the Swans leadership group, so it was too soon to say if the group would take disciplinary action.

"For whatever reason it's happened twice now in the space of around 15 weeks. So there is the issue of the Bloods' code but we haven't even got around to addressing it from a discipline point of view.

"But we certainly hope to get him back playing with the Swans."

Roos added it was of more importance that Hall sorts out his own mental processes.

"We as a footy club just can't put Barry in a position where he's not capable of handling that situation. The main issue for Barry right now is to try to get himself in a space where he can perform."

Hall will continue to work with the club's psychologist.

"Grant will determine when he can play again," said Roos, who added he'd leave it up to Hall whether he wanted to train with the group or not.

Roos described Hall's reaction as "shock" at how this latest situation has panned out for the 31-year-old spearhead.

Roos added that he noticed a slight change in the player's personality in the lead up to the Collingwood match, describing the spearhead as "quiet" in team meetings.

"We'll work through with Hally so we can come to a suitable conclusion," said Roos. But also you have got to remember we've got to play a game of footy this weekend against Hawthorn."
